DESCRIPTION

The MP8007 is an integrated IEEE 802.3af compatible PoE Powered Device with PD interface and power converter. It is targeted for isolated or non-isolated 13W PoE application.

The PD interface has all the functions of IEEE 802.3af, including detection, classification, 120mA inrush current, 840mA operation current limit as well as 100V Hot-swap MOSFET.

The DCDC converter uses fixed peak current and variable frequency discontinuous conduction mode (DCM) to regulate constant output voltage. The primary-side regulation without opto-coupler feedback in flyback mode simplifies the design while buck mode continues minimizes the solution size for nonisolated applications. A 180V integrated power MOSFET optimizes the device for various wide voltage applications.

The MP8007 features protection including over current protection, over voltage protection, open circuit protection and thermal shutdown.

The MP8007 can support a front-end solution for PoE-PD application with minimum external component, it is available in QFN-28 (4mmX5mm) package.
